Researchers study link between human genes and dengue

SINGAPORE - With just a gargle, you may soon find out if you are prone to severe dengue. Researchers at Tan Tock Seng Hospital and Genome Institute of Singapore are studying how the human genes can define the development of dengue in an infected person. Past dengue patients from Tan Tock Seng Hospital must gargle 10 millimetres of mouthwash and then spit it into a container - which is then sent to a lab for testing. From the sample, researchers will analyse the link between genetic factors and disease outcomes. They hope to differentiate individuals with mild to severe dengue. Since April this year, 300 dengue patients have been tested. The study will help doctors in the early identification of dengue patients at risk of developing severe dengue. Currently, there is no vaccine available to protect against dengue. Patients are given supportive care with intravenous fluids a...
